Proportions are something best worked out before you get to pixel-level detail. Sketch or block in the body parts without worrying about making nice, smooth shapes or details like clothing, then add details and clean up afterwards. If you aren't sure what the proportions should
be, there are
plenty of proportion charts out there.
You dove into details too early, before taking the time to work out her proportions and pose. Also, if the 128x128 size is your working size and not a crop: I highly recommend working on a larger canvas than you need, so you don't find yourself squishing things in. It's easier to crop later than try to fight off the subconscious urge to distort things to fit.
Here are a couple of possibilities, one more realistic, one with anime/supermodel legs:


Like Hagane wrote, I made the crotch-heel distance equal to the head-heel distance. On a realistic person, the "crotch" position is higher, the anime legs have the "crotch" as being at the bottom, where the crotch ends. Note that it's the crotch-
heel distance, meaning the distance to the heel of the foot, not of the whole leg. A character wearing high heels will have legs that look longer because of the way the foot is positioned. That's why the guidelines in my sketches don't reach the "floor".
The character's head is rather large, so the longer legs will probably feel more proportionate. The shorter legs would look better on a character with a more realistically-sized head.
Also notice how rough I made the sketch. This is because the goal is to just work out the proportions.
